如何在golang中比较字符串？ [关闭]

Question

I want to make a function that calculates the length of the common segment (starting from the beginning) in two strings. For example:

foo:="Makan"
bar:="Makon"

The result should be 3.

foo:="Indah"
bar:="Ihkasyandehlo"

The result should be 1.

Answer 1

You mean like this. Please note, this will not handle UTF 8, only ascii.

package main

import (
    "fmt"
)

func equal(s1, s2 string) int {
    eq := 0
    if len(s1) > len(s2) {
        s1, s2 = s2, s1
    }
    for key, _ := range s1 {
        if s1[key] == s2[key] {
            eq++
        } else {
            break
        }
    }
    return eq
}

func main() {
    fmt.Println(equal("buzzfizz", "buzz"))
    fmt.Println(equal("Makan", "Makon"))
    fmt.Println(equal("Indah", "Ihkasyandehlo"))
}
